Which product is required to enable single sign-on in Oracle Fusion Middleware?

To enable single sign-on (SSO) in Oracle Fusion Middleware, Oracle Access Manager is the required product. This tool is specifically designed to facilitate secure and streamlined access to web applications by allowing users to authenticate once and gain access to multiple applications without needing to log in again for each one.

Oracle Access Manager provides essential features such as identity federation, centralized authentication, and access control, which are crucial for implementing an SSO solution. It integrates with various identity stores and can work with multiple protocols to authenticate users efficiently across diverse systems in an enterprise environment.

In contrast, while Oracle Identity Management is involved in managing user identities and their access privileges, it is not the primary product for enabling SSO by itself. LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and maintaining directory information services but does not provide SSO functionality directly. Oracle Security Management encompasses broader aspects of security, including securing applications and data, but again, it does not specifically target the single sign-on capability that Access Manager provides.

Therefore, Oracle Access Manager is the dedicated solution required for implementing single sign-on in Oracle Fusion Middleware, making it the correct choice.
